Hello! I looked up the motors in question, and they are used in RC boats, planes,and wheeled vehicles. The reviews on the internet give them a good performancerating, and they are used quite frequently in robotics projects. I have not located anyreports of burn outs, or, if the motor will hold its position. Will have to look further into it.Keep me posted......

Hello!I have found some information from the book,programming the propeller with SPIN; a beginnersguide to parallel processing.(page 204)Futaba servos need to have a pulsed signal sent to them approximately60 times a second on a regular basis to accurately maintain their commandedposition. If this is not done, the operation of the motors becomes jerky andirregular. The requirement also means that there can be a minimum worst-casedelay of about 1/60th of a second whenever a command is sent to an R/C servo.For all practical purposes, a lag this long is not critical in a motor application.However, you need to have in mind that this delay does exist. It takes1/60th of a second(worst case) for the motor to start responding to thelast command sent to it. The servos have to be reminded of their position about 60 times a second inorder to maintain proper operation, so , we need a way to pulse the servoson a regular basis 60 times a second.This programming is assumed to be in every robot that uses these types of servos.Whew!
